Association of an electromyographic tube for severe postoperative laryngeal edema and reintubation in neurosurgery: a retrospective study

Hiroki Matsushita, Kazuhiro Shirozu, Kaoru Umehara, Kenji Uehara, Makoto Takatori & Ken Yamaura

doi : 10.1007/s00540-021-02953-5

Journal of Anesthesia volume 35, pages611–616 (2021)

An electromyographic (EMG) tube is sometimes used for vagal nerve monitoring during neurosurgery. Some characteristics of an EMG tube are different from those of a normal endotracheal tube. Although postoperative laryngeal edema (PLE) may occur and reintubation may be required in some patients in whom an EMG tube is used, its relevance to these events has not been investigated in detail. Our goal was to determine the relevance of an EMG tube to the development of PLE and the need for reintubation.

Need for preoperative anemia management clinics in Japan: initiatives at a university hospital in the USA

Patrick Hussey, Yoshiko Onodera, Sundara Reddy, Blain Samuelson, Sudhakar Subramani, Yatish Siddapura Ranganath, Tariq Jaradat & Satoshi Hanada

doi : 10.1007/s00540-021-02979-9

Journal of Anesthesia volume 35, pages710–722 (2021)

Untreated preoperative anemia increases the risk of morbidity and mortality and there is increasing evidence that early intervention for preoperative anemia improves outcomes after major surgery. Accordingly, anemia management clinics have been established in various institutions in the USA. As an example, the University of Iowa Hospitals and Clinics outpatient clinic treats pre-surgical anemic patients, who undergo major surgery with anticipated blood loss of more than 500 mL, by providing effective standardized care in a timely manner. This standardized care is an integral part of patient blood management to reduce perioperative blood transfusion and improve patient outcomes. The importance of preoperative anemia management has not yet been sufficiently recognized in Japan. Timely intervention for preoperative anemia should be incorporated into routine pre-surgical patient care in Japan.

Comparison of PECS II and erector spinae plane block for postoperative analgesia following modified radical mastectomy: Bayesian network meta-analysis using a control group

Boohwi Hong, Seunguk Bang, Chahyun Oh, Eunhye Park & Seyeon Park

doi : 10.1007/s00540-021-02923-x

Journal of Anesthesia volume 35, pages723–733 (2021)

The present study compared the effects of pectoral nerve block II (PECS II) and erector spinae plane (ESP) block for postoperative analgesia in patients who underwent modified radical mastectomy by performing a network meta-analysis (NMA) using indirect comparison with systemic analgesia. Studies comparing the analgesic effects of PECS II and ESP block were searched on MEDLINE, PubMed, EMBASE and the Cochrane Library. The primary outcome of this study was cumulative opioid consumption for 24 h postoperatively. Pain score during this period was also assessed. NMA was performed to compare the postoperative analgesic effects of plane blocks and systemic analgesia. A search of databases identified 17 studies, with a total of 1069 patients, comparing the analgesic efficacies of PECS II block, ESP block, and systemic analgesia. Compared with systemic analgesia, mean difference of opioid consumption was ??10 mg (95% credible interval [CrI] ??15.0 to ??5.6 mg) with PECS II block and ??5.7 mg (95% CrI ??11.0 to ??0.7 mg) with ESP block. Relative to systemic analgesia, PECS II block showed lower pain scores over the first postoperative 24 h, whereas ESP block did not. PECS II block showed the highest surface under the cumulative ranking curves for both opioid consumption and pain score. Both PECS II and ESP blocks were shown to be more effective than systemic analgesia regarding postoperative analgesia following modified radical mastectomy, and between the two blocks, PECS II appeared to have favorable analgesic effects compared to ESP block.

ORi™: a new indicator of oxygenation

Yusuke Ishida, Toshio Okada, Takayuki Kobayashi & Hiroyuki Uchino

doi : 10.1007/s00540-021-02938-4

Journal of Anesthesia volume 35, pages734–740 (2021)

In the perioperative period, hypoxemia and hyperoxia are crucial factors that require attention, because they greatly affect patient prognoses. The pulse oximeter has been the only noninvasive monitor that can be used as a reference of oxygenation in current anesthetic management; however, in recent years, a new monitoring method that uses the oxygen reserve index (ORi™) has been developed by Masimo Corp. ORi is an index that reflects the state of moderate hyperoxia (partial pressure of arterial oxygen [PaO2] between 100 and 200 mmHg) using a non-unit scale between 0.00 and 1.00. ORi monitoring performed together with percutaneous oxygen saturation (SpO2) measurements may become an important technique in the field of anesthetic management, for measuring oxygenation reserve capacity. By measuring ORi, it is possible to predict hypoxemia and to detect hyperoxia at an early stage. In this review, we summarize the method of ORi, cautions for its use, and suitable cases for its use. In the near future, the monitoring of oxygen concentrations using ORi may become increasingly common for the management of respiratory function before, after, and during surgery.

Hypoxia-dependent signaling in perioperative and critical care medicine

Kiichi Hirota

Journal of Anesthesia volume 35, pages741–756 (2021)

A critical goal of patient management for anesthesiologists and intensivists is to maintain oxygen homeostasis in patients admitted to operation theaters and intensive care units. For this purpose, it is imperative to understand the strategies of the body against oxygen imbalance—especially oxygen deficiency (hypoxia). Adaptation to hypoxia and maintenance of oxygen homeostasis involve a wide range of responses that occur at different organizational levels in the body. These responses are greatly influenced by perioperative patient management including factors such as perioperative drugs. Herein, the influence of perioperative patient management on the body's response to oxygen imbalance was reviewed with a special emphasis on hypoxia-inducible factors (HIFs), transcription factors whose activity are regulated by the perturbation of oxygen metabolism. The 2019 Nobel Prize in Physiology or Medicine was awarded to three researchers who made outstanding achievements in this field. While previous studies have reported the effect of perioperatively used drugs on hypoxia-induced gene expression mediated by HIFs, this review focused on effects of subacute or chronic hypoxia changes in gene expression that are mediated by the transcriptional regulator HIFs. The clinical implications and perspectives of these findings also will be discussed. Understanding the basic biology of the transcription factor HIF can be informative for us since anesthesiologists manage patients during the perioperative period facing the imbalances the oxygen metabolism in organ and tissue. The clinical implications of hypoxia-dependent signaling in critical illness, including Coronavirus disease (COVID-19), in which disturbances in oxygen metabolism play a major role in its pathogenesis will also be discussed.

Fibrinogen measurement by a novel point-of-care device with whole blood: comparison of values against Clauss method

Shoko Okahara, Tetsuya Handoh, Mitsuru Wakita, Takamasa Yamamoto, Shigeki Misawa, Takashi Miida & Hiroyuki Sumikura

doi : 10.1007/s00540-021-02987-9

Journal of Anesthesia volume 35, pages757–760 (2021)

Timely fibrinogen replacement is key to treating critical hemorrhage. Measuring fibrinogen concentration by conventional laboratory tests requires centrifugation of blood samples and is often time-consuming. A point-of-care testing device (A&T, Yokohama, Japan), CG02N, has been available in Japan since 2011 to measure fibrinogen concentration without centrifugation. However, it has not been widely used as it requires dilution of blood samples using manual micropipetting. To further speed up and simplify the fibrinogen measurement, an improved device called FibCare (Atom Medical, Tokyo, Japan) was developed to avoid diluting blood samples. The purpose of this study is to verify the reliability of FibCare against laboratory measurement using the Clauss method. Fibrinogen concentrations with 60 sodium citrated whole blood samples were measured by both FibCare and Clauss methods in the laboratory. Measured values with the Clauss method were distributed in the 88–300 mg/dL range. By comparing these results, a significant positive correlation was observed between the FibCare and Clauss method (Y?=?12.402?+?0.982 X; R?=?0.891; P?<?0.01). The study indicated that FibCare allows accurate measurement of fibrinogen concentration and shows a possibility to contribute to optimal fibrinogen replacement therapy during critical hemorrhage.

Unique strategy using a standard double lumen tube during one lung ventilation for successful intraoperative airway management in patients with a giant bulla on the ventilated side: case series

Izumi Kawagoe, Masakazu Hayashida, Daizoh Satoh, Osamu Kudoh, Masataka Fukuda, Tsukasa Kochiyama, Jun Kishii & Chieko Mitaka

doi : 10.1007/s00540-021-02991-z

Journal of Anesthesia volume 35, pages761–766 (2021)

Giant lung bullae are usually seen in patients with severe chronic obstructive pulmonary disease. Over time, air trapping leads to severe dyspnea and CO2 accumulation. In severe cases, overinflation and rupture of the bulla can cause secondary life-threatening tension pneumothorax. Since positive pressure ventilation exerts deleterious effects on the bulla, general anesthesia is always challenging in patients with giant bullae. We encountered remarkable intraoperative hypercapnia and decreased tidal volume in a 58-year-old male patient with bilateral bullae who underwent right upper bullectomy, due to overinflation of a bulla located in the upper lobe of the ventilated side. Through this experience, to avoid further overinflation, we devised an original, unique and simple airway management strategy using a standard double lumen tube (DLT), which only requires slightly deeper advancement of the DLT to achieve selective lobar blockade during one lung ventilation (OLV). Following the first case, we used this strategy in a 48-year-old male patient who underwent left giant bullectomy, resulting in successful airway management without overinflation during OLV. We recommend our strategy as an option for successful intraoperative airway management during OLV in select bullectomy patients with bilateral giant bullae.
